  EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)

  Gone are the days with too many cables. With the EmStat4 MUX you have a potentiostat and a multiplexer in one! The EmStat4 MUX is a powerful potentiostat, galvanostat and impedance analyzer and supports all popular electrochemical techniques. Its 8 channels allow for sequential measurements, for example eight Screen-printed electrodes, or eight working electrodes in eight different  cells.  The instrument’s measurements can be highly customized using MethodSCRIPT. The 4 different cell connections available allow for many different setups. When the measurements are finished, you can easily save your results in PSTrace, or export your results to Excel.

  • Integrated 8-channel multiplexer
  • Supports 2-, 3- and 4-electrode setup using Sense Lead
  • Potential range: ± 3V 
  • Compliance voltage: ± 5V
  • Current ranges:  1 nA – 10 mA
  • Maximum current: ± 30 mA
  • FRA / EIS up to 200 kHz

  Two modes of operation

  • Consecutive mode: this mode switches channel when a complete measurement has finished
  • Alternate mode: this mode switches all activated channels within the specified time interval of a measurement.

  In both modes the unselected Working Electrodes can either be left floating or switched to Ground to keep the specified voltage.

  Supports a 2-, 3- or 4-electrode setup

  • Connect four electrodes per channel by using the Sense Leads. 
  • Or connect only three electrodes per channel by internally connecting all Sense electrodes to the Working Electodes in software.
  • Do you need to connect only two electrodes per channel? Combine the reference and counter electrode physically on the cable, or with a single click on the PSTrace software.

  

  8 to 128 channels

  Is 8 channels not enough? If more channels are required, one or more MUX-R2 can be stacked to the EmStat4 MUX for a total of up to 128 channels.

  Script your experiments!

  Via the script window of PSTrace it is possible to perform a different experiment on each of the channels sequentially. Alternatively, you can use MethodSCRIPT to fully customize your measurements per channel.

  Multichannel or Multiplexer?

  To make it easier for you to decide, if  a multiplexer or a multichannel device is more suitable for your application, we have created a short explanation of multiplexers and multichannels.

  Basic electrochemical H-cell setup (redox.me)

  This is a stationary solution double compartment electrochemical H-Cell for measurements of electrodes in a form of:

  a) rod/disc (6 mm dia.),

  b) thin film deposited on a flat substrate (using a wire clip) and

  c) membrane (using a wire clip).

   

  The working, counter and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The counter electrode is placed in a compartment separated from the other electrodes by ion-exchange membrane (19 mm to 25 mm dia.), so the electrochemical products appearing at working and counter electrode do not affect the opposite electrode. The counter electrode compartment is equipped with a separate inlet and outlet for easy filling with an electrolyte and evacuation of gaseous products. It can accommodate standard Metal Wire Auxiliary Electrode as well as square shape electrodes with sizes up to 25 mm x 25 mm. The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte. After removal of the counter electrode glass compartment, the cell gets the functionality of a Basic Electrochemical Cell – BEC 50 mL. 

  The cell chamber is available in several material variants here.

   

  Application note:
  The reference electrode tip and working disk electrode tip should be placed in the middle of the membrane. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil/mesh/foam electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment. 

   

  Specification:
  minimum electrolyte volume in WE compartment: 22 mL
  minimum electrolyte volume in CE compartment: 6 mL
  maximum electrolyte volume: 40 mL
  minimum membrane diameter: 19 mm
  maximum membrane diameter: 25 mm
  maximum membrane thickness: 0.5 mm
  electrode plug diameter: 6 mm
  number of electrode slots: 3

   

  Intrastat data:
  HS Code: 90309000
  Country of Origin: Sweden
  NET weight: 200 g

   

  Setup includes:
  1 x BE H-Cell 50 mL – Basic Electrochemical H-Cell 50 mL
  1 x Metal Wire Auxiliary Electrode – 50HX15 0.6/250 mm (Platinum)
  1 x Reference electrode (Ag/AgCl, or Ag/Ag+)
  1 x Glassy Carbon disk electrode – 2 mm dia.
